I have a MCC USB-205 DAQ, the speed of it is very less because it doesnt support foreground and background operations. I thought of writing an MEX file to increase the speed of it. I downloaded the code from but i get the following errors,
>>mex digCode.c
Building with 'MinGW64 Compiler (C)'.
Error using mex

collect2.exe: error: ld returned 1 exit status
Can anyone help me with it. Where can i find supporting documents to write mex file for mcc daq.

This is standard compiler options. -I (capital eye) to name a directory that holds include files. -l (lower-case ell) to indicate the basic name of a dll to link against. -L (capital ell) to indicate a directory that holds dlls to link against (you would typically use -L to name the directory and then -l to name the library in the directory)
